Possessing small amounts of marijuana is now legal in the nation’s capital, even after some members of Congress threatened prison time for D.C. Council members.

Mayor Muriel Bowser and other officials issued a response to Capitol Hill during a briefing Wednesday afternoon, saying the city would move forward with the law.

Bowser said the city and Republicans in Congress disagree about whether the city is allowed to legalize pot but those legal differences can be resolved without either side bullying or threatening the other.

“We believe that we are acting lawfully,” Bowser said.

Bowser said the law was enacted Dec. 5 when the vote for Issue 71 was certified by the Board of Elections. Council Chairman Phil Mendelson said they had no choice but to send it to Congress for a 30-day review under the Home Rule Act.

“This is the process that we have to follow when legislation has been enacted,” Mendelson said.

But Congress is investigating D.C.’s move, and one representative is demanding documents showing how money has been spent to change the city’s pot laws.
